telling you to bring it in at 1300 is ****ing dumb. DO NOT TAKE IT BACK AT 1300 MILES. if you called them and they confirmed it, either they are completely mistaken, you are mistaken, there is some unknown circumstance necessitating this 1300 mile oil change we don't know about, or they are just trying to take your money. i really don't see any other scenario out there. just stick to the manual as Yamaha has directed and your bike will thank you: 4,000 mile oil change, 8,000 mile oil change, etc. and i would recommend taking it to a different shop in the future if they are trying to swindle you.
